Answer:
Mitch made a mistake in step 1.
Step-by-step explanation:
7.7 = w - 2
Add two to both sides
7.7 + 2 = w - 2 + 2
9.7 = w is the right answer.

f(x) = -7x + 1, find f(-2) x
f=-2
Okay, so basically just plug -2 in for x in the equation and solve.
-7(-2) + 1
Multiply first

What is the slope m in the equation y = -2x + 5
Answer:
m = -2
General Formulas and Concepts:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step-by-step explanation:
Step 1: Define function
y = -2x + 5
Step 2: Break function
Slope m = -2
y-intercept (0, 5)
Suppose the graph of a cubic polynomial function
has the same zeroes and passes through the
coordinate (0, -5).
Describe the steps for writing the equation of this
cubic polynomial function.
DONE
Answer:
Use the zeroes to determine the roots.
Write the polynomial as a product of the leading coefficient, a, and the factors, where each factor is x minus a root.
Use the y-intercept (0, –5) to solve for the leading coefficient.
Substitute the leading coefficient into the polynomial function for a and simplify.
Step-by-step explanation:
Use the given conditions to find the exact value of the expression.

Answer:
(7 -24√3)/50 = 0.14 -0.48√3
Step-by-step explanation:
Sine is negative and cosine is positive in the 4th quadrant, so ...
sin(α) = -√(1 -cos(α)²) = -√(1 -576/625) = -7/25
Then the cosine of the angle sum is ...
cos(α +5π/6) = cos(α)cos(5π/6) -sin(α)sin(5π/6)
= (24/25)(-√3/2) -(-7/25)(1/2)
= (7 -24√3)/50 = 0.14 -0.48√3

A auto manufacturer claims that one of its car brands has mean MPG (miles per gallon) rating of 40 on the highway. Identify Type I error for this claim.
a. Fail to reject the claim that mean is 40 MPG when it is actually 40 MPG.
b. Fail to reject the claim that mean is 40 MPG when it is actually not 40 MPG.
c. Reject the claim that mean is 40 MPG when it is actually not 40 MPG.
d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.
Answer:
d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.
Step-by-step explanation:
The type 1 error could be said to have been made if the null hypothesis is erroneously rejected.
In the scenario above :
The null hypothesis (H0) : mean = 40
Hence, if the Null hypothesis defined above is rejected when in fact the hypothesis that the mean miles per gallon is actually 40.
On the other hand, the type 2 error occurs when a null which is false is not rejected.
Hence, when a true null is rejected, a type 1 error is committed. Similarly, when a false null isn't rejected, then a type 2 error has been committed.

Find the equation of the line that is perpendicular to the given line and passes through the given point.
Enter the right side of the equation as a single fraction.
y =

-;(1,1)
4
The equation is y =
Answer:
y=(5x-3)/4
y=(5/4)x-3/4
Perpendicular slops come from reversing the numerator and denominator and making it negative so the new slope would be:
m=-4/5
Then you use point slope formula and plug in your values:
y-y1=m(x-x1)
y-1=-4/5(x-1)
y=(-4/5)x+9/5

Is the amount of time it takes to download a file from the internet discrete or continuous?
Answer:
The amount of time that is spent downloading internet files is a continuous measurement and is not discrete, because it will always follow the same length of time that is estimated to download, but due to changes of internet WiFi connectivity and other background programs this can all affect the speed of the computer programs responsible for downloading the files.
Answer/Step-by-step explanation:
The amount of time that is spent downloading internet files is a continuous measurement and is not discrete, because it will always follow the same length of time that is estimated to download, but due to changes of internet WiFi connectivity and other background programs this can all affect the speed of the computer programs responsible for downloading the files.
Please find measure of angle s. PLEASE HELP FAST!!
Answer:
27
Step-by-step explanation:
15x-31 = 9x+11
6x-31 = 11
6x = 42
x = 7
15x -31 + 9x + 11 + s = 180
15(7) -31 + 9(7) + 11 + s = 180
105 - 31 + 63 + 11 + s = 180
153 + s = 180
s = 27
Which fraction is equivalent to 2/3 explain
Answer:
4/6, 8/12, 20/30
Step-by-step explanation:
They are equivalent to 2/3, because they can all be simplified to 2/3.
For example, 2 x 2 = 4 and 2 x 3 = 6; this gives me 4/6. I multiplied 2/3 by 2/2.
SO it can also be 2/3 = 4/6= 6/9 = 8/12 = 10/15 = 12/15 = 15/18 = 18/21 = 21/24 etc.

Answer:
What do you mean by combining terms?
If you have an equation like y=3(2+x), then you would need to substitute for x before you combined the terms "2" and "x"
Investors buy a studio apartment for 140,000. Of this amount, they have a down payment of 35,000. Their down payment is what percent of the purchase price? What percent of the purchase price would a $56,000 down payment be?
Answer:
25%40%Step-by-step explanation:
Cost of apartment = 140000Down payment = 35000Down payment of 35000 is:
